From Anidb: “It has been half a year since the threat of the Harmonium was defeated and each Otome has gone to chase her respective dream. The Pearl Otome Irina has, with help from Yohko, recovered a technology that could resurrect Erstin, which she intends to use in order to salvage the lost time with her deceased friend. Unfortunately for her, the use of such technology is forbidden. Meanwhile, the Otome and the Aswad have joined forces for an attack on the headquarters of Schwarz.” More Mai Otome images after the jump
Summary: “One year after the events of Mai-Otome, an asteroid on a collision course with Windbloom kingdom is destroyed – barely – by an international task force of Meister Otome. Subsequently a new and more powerful kind of Slave appears, along with a sinister black-robed entity – or entities – able to easily overpower the most powerful of Meisters. Not only this, but Arika and Mashiro’s troubled relationship is hindering the use of the Sapphire of Azure Sky – possibly the one weapon powerful enough to defeat this new adversary.” [ Anime News Network ] [ Official Site ]
